'.' My 1 invention relates to devices f or dispensinga'liquidinsecticide. I

- It isan important object ofthe invention to improve upon theartparticularly relating to the control of Argentine and sweet eating ants,and

in the furtherance-of th-is purpose additional objects reside in theimprovement of such devices wherein a more up-to-date feeding means iseffected; the improvement relating to the prevention of the delivery ofthe poisonous feed to the creatures previous to the device being put touse; the improved vent means for controlling the feed and the improvedmeans for positioning the feeding means making the latter moreaccessible, whereby the ants are enticed to their destructive end.

A more specific object of the invention is to provide an improved porousplug arrangement for Fig. 2 is a perspective view of the lid, gasket,

and sealing cap in extended relation, and,

Fig. 3 is an end elevation of the dispensing end.

Referring in detail to the drawing, the container 5 shown thereindesirably consists of a bottle or small glass jar, the body portion ofwhich is of an approximately rectangular character having a widthgreater than its thickness. This body is shown furnished at one end witha protruding neck portion 6 having around its inner or basal portion acircumferential bead 1 and farther out with a spirally inclined bead 8.With the latter bead cooperates the internal spiral grooves or screwthreads 9 of the attaching flange I of a sheet-metal closure cap ll whensaid cap is screwed into place.

Said cap ii] is furnished near its periphery with an outwardly directedannular lip or flange l3 which surrounds a liquid delivery opening whichis partially obstructed by a plug l4, said plug being sufficientlyporous to permit the liquid poison to gradually ooze through it from theinterior of the container. The screw-threaded connecting means betweenthe cap and bottle neck is so arranged as to cause complete screwingdown of the jacent to mid-Width portion of one of the fiat sides of thecontainer so that, when such side is placed upon a supporting surfacethe poison delivery orifice will be near the lower side of the containerwhere it will be attractive to ants crawling 5- oversuch. supportingsurface. When the cap is screwed down its delivery aperture is slightlyspaced awayfrom the inner edge of an annular gasket l5 positioned withinthe peripheral portion I of the cap as shown in Fig. 1.

In order to guard against any escape-of the con tents of the container:through the porous plug l4 before the article is to be used, a circularsealing disk I6 is provided to fit between the annular gasket i5 and themouth of the container, said disk having a radially extending peripheralfinger I! to facilitate its manual removal or replacement.

The portion of the cap H which is uppermost when the device is in itsoperative position is furnished with a radially extending out-pressedridge or bead l9, thus providing underneath this outpressed part agroove 20 to prevent an internal vacuum from occurring and arresting theliquid contents 2| from oozing out through the porous plug I4 when thedevice is-positioned for use. Said out-pressed ridge not only extendsacross a face portion of the cap bordering ,upon its periphery, but apart 22 of this ridge extends down along the flange Ill of thecapasufficient distance to insure that an air passage is afforded backof a brim bead-23 which surrounds the mouth of the neck portion 6 of thecontainer.

When the device is to be put into use, the cover is removed and then theuser by manually grasping the finger ll of the sealing disk I6 removessaid disk. Then the cover is again screwed on and, owing to the absenceof said sealing disk, air can readily enter by the inlet 20 tofacilitate the gradual fio'w of the liquid poison through the porousplug l4. 40

The container is then positioned upon the ground or other supportingsurface in a position wherein it rests upon that one of its two flatsides which is adjacent to the plugged outlet it. Thus positioned, thesweetened poison is brought close to the surface over which will crawlthe ants or other insects to be destroyed. Hence, such insects areeffectively attracted to, and caused to partake of the insecticide.

It should be understood that the present disclosure is for the purposeof illustration only and that this invention includes all modificationsand equivalents which fall within the scope of the sub- 'ject matterclaimed.

1. In an article of the kind described, a container having a fillingopening surrounded by an externally screw-threaded neck, a cap having aflange capable of being screwed down upon said neck until its bodyportion abuts against the end thereof, said cap having a partiallyobstructed liquid delivery opening through its body portion in anadjacent, spaced relation to its periphery,

an annular gasket interposed between the end of the neck of saidcontainer and the body portion of said cap, said gasket beingsufiiciently narrow to avoid overlying said liquid delivery opening whenthe cap is applied, and a disk shaped gasket at such time interposedbetween said annular gasket and the end of the neck of the container,the latter gasket having a radial finger to facilitate its manualinsertion and removal.

2. As an article of manufacture, a sheet-metal cap for poison dispensingreceptacles, said cap having a delivery opening through its body portionnear its periphery and having an attaching flange of a screw-threadednature for securing it to the neck portion of a container, said caphaving also an outpressed bead which extends radially over the part ofits peripheral portion which is opposite to said delivery opening, saidhead being continued across a portion of the width of the attachingflange of said cap.

3. In an article of the kind described, a container having a fillingopening surrounded by a neck which is externally screw threaded, saidneck having an outwardly directed external bead around the extremity ofits mouth portion; and a sheet-metal cap for said neck portion providedwith a flange having screw elements adapted to screw onto the threadedportion of said neckto form a closure for said container, said caphaving a delivery opening located near one side of the periphery of itsbody portion and having a bead extending radially across the marginalpart of its opposite peripheral portion, said head being continuedacross a part of the flange of said cover thereby affording an airrelief passage, one end of which communicates with the spacecircumscribed by the neck portion of the container and the other endportionof which extends behind the aforementioned bead and by means ofthe threaded portion of the neck of the container communicates with theexternal atmosphere when the cover is applied to the receptacle.
